With efficacy and service life steadily increasing and costs declining by about 18 percent each year (Memoori, 2014), the LED revolution continues to develop at a rapid pace. LED’s inherent compatibility with digital control, aided by other trends, is setting the stage for the next LED revolution: smart lighting control. Many LED products are sold […]
Lutron’s Dr. Pekka Hakkarainen recently wrote an article for LEDs MAGAZINE that makes the case that further LED adoption depends on advanced lighting controls. Check it out here.
The Illuminating Engineering Society, in partnership with the Lighting Controls Association, has published LEM-7, Lighting Controls for Energy Management, a detailed guide to energy-saving lighting controls. The publication was written by Craig DiLouie, LC in support of the IES Energy Management Committee. The 48-page 8.5×11 guide, which is available for $35 (IES members) and $50 […]
ELECTRICAL CONTRACTOR recently published an article, written by Craig DiLouie, LC, defining a new dimension of lighting control–white light color tuning. Check it out here.
Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy Solid-state lighting has proven that it can deliver high-quality light with substantial energy savings in many applications. But dimming can still be an issue, as CALiPER testing and GATEWAY demonstrations have shown. This concern was […]
ARCHITECTURAL LIGHTING recently published an article about flicker with LED lighting, particularly problematic in some dimming scenarios. Click here to read it.
The U.S. Department of Energy (DOE) has published a new report, Dimming LEDs with Phase-Cut Dimmers: The Specifier’s Process for Maximizing Success. The report was created in response to issues raised about dimming by energy efficiency organizations and specifiers, and is based on experience from CALiPER testing and GATEWAY demonstrations. While progress has been made […]
The Alliance for Solid-State Illumination Systems and Technologies (ASSIST), a program of the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, recently released a new publication that addresses the issue of how lamps should dim in terms of their “look and feel” during the dimming process. The publication, ASSIST recommends… Dimming: A Technology-neutral Definition, provides […]
In 2012, University of California-Davis upgraded its exterior lighting as part of its Smart Lighting Initiative. Wall packs on campus, like other exterior luminaires, were retrofitted with dimmable LED sources, motion sensors and wireless controls. This allowed the units to be incorporated into an adaptive campus-wide lighting control system. The system offers an intelligent, networked […]
Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy The U.S. Department of Energy (DOE) recently released a GATEWAY report on a parking-garage demonstration conducted at U.S. Department of Labor (DOL) headquarters in Washington, DC, which serves as a classic illustration of the savings […]
